ALFRED H. ANSTEY, OF CHESTER, PENNSYLVANIA.

BUMPER FOR SASH-FASTENERS.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed March 7,1907. Serial No. 361,058.

To all whom it may concern:

Be it known that I, ALFRED H. ANsTEY, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Bumpers for Sash-Fasteners, of which the following is a specification.

This invention relates to sash-fasteners, and has for its object to provide a bumper for such a device to prevent scairing or deiacement of the head of the windowframe.

In the accompanying drawing, Figure 1 is a vertical cross-section of a window and its frame showing the application of the invention. Fig. 2 is a front elevation partly in section. Fig. 3 is an elevation partly in section showing a modification.

Referring specifically to the drawing, 5 denotes the head of the window-frame; 6 the meeting-rail of the upper window sash; and 7 the meeting-rail of the lower sash; The sash-fastener comprises a keeper 8 which is carried by the meeting-rail of the upper sash, and a locking-lever 9 which is rotatably mounted on a stud 10 rising from a base 11 carried by the meeting-rail of the lower sash. The stud has a threaded extension 12 above the lever 9 to receive a screw-cap 13 for holding the bumper 14 which is placed inside the cap and projects therefrom to the outside through an opening 15 in the top of said cap. The bumper has a flange 16 whereby it is securely clamped between the end of the extension 12 and the top of the cap 13 when the latter is screwed down, and is thus prevented from pulling out through the opening 15. When worn the bumper can be readily removed and replaced by unscrewing the cap 13, and this can be done without disturbing the sash-fastener.

As an additional precautionary measure, in case the bumper should be broken off, the head of the windowframe is fitted with a pad 17 where the bumper strikes. The bumper and pad are made of rubber or other suitable elastic material.

In the modified form shown in Fig. 3 the bumper is a button 18 having a stem 19 which fits in a socket 20 formed in the top of an enlarged extension 21 of the stud 10.

I claim 1. The combination with a sash-fastener member com prising a base, a stud rising from the base, and a locking lever rotatably mounted on the stud, of an elastic block mounted on the end of the stud.

2. The combination with a snslriastencr member, of a threaded stem rising therefrom, a cap screwed on the stem and having an opening in its top, and an elastic block clamped between the end of the stem and the top of the cap, and projecting to the outside of the cap through the aforesaid opening.

In testimony whereof I aiiix my signature, in presence of two Witnesses.

ALFRED II. ANS'LEY.
